MACHINE FOR FORMING HORSESHOE-BLANKS.

SPECIFICATION forming part of Iletters Patent No. 498,839, dated June 6, 1893.

Application filed June 14, 1892.

To all whom it may concern: i

Be it known that I, JOHN DOUGLAS BIL- LINGs, a citizen of the United States, residing at the city of New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Machines for Forming Blanks for Use in the Manufacture of Horseshoes, of which the following is a specification.

My present invention relates in general to that type of machines for forming blanks for horseshoes, which are provided with complemental reciprocating and rotary dies for rolling hot metal bars into blanks provided with I 5 calks and with indentations for nail holes and suitable for being cut up and bent into horseshoes; and it relates more particularly to mechanism for driving oractuating the complemental dies.

The principal objects of my present invention are first, to provide mechanism for uniformly operating or driving the dies untilone or more blanks adapted to be out up into pieces corresponding to the length of one or more horseshoes have been formed, and for automatically stopping the dies as soon as the above resulthas been accomplished,whereby the blanks are rolled of uniform length and Waste of rolled metal in cutting up the same is avoided; second, to provide simple, inexpensive and efficient means under the control of the operator for rapidly returning the dies to their normal positions upon the completion of a single or series of blanks; 3 5 third, to provide simple devices for checking the return motion of the dies as soon as the latter are in their proper initial positions; and fourth, to cause the rotary and reciprocating dies to travel uniformly with precisely the same surface velocity, thus preventing one of the dies from lagging or dragging behind the other and insuring the production of perfect work.

My invention consists of a machine for form- 4 5 ing metal bars into horseshoe blanks provided with complemental reciprocating and rotating dies, a positively driven gear-wheel and suitable gearing interposed between said gearwheel and each of said dies. a,

59 My invention further consists of a machine Serial No. 436,701. (No model.)

for forming metal bars into horseshoe blanks provided with com plemental reciprocating and rotating dies, a countershaft, gear wheels interposed between the rotary die and counter-shaft, a rack and pinion interposed between the reciprocating die and counter-shaft, and means for actuating the counter-shaft, whereby said dies areconjointly driven in the same direction with a uniform surface velocity. V

My invention further consists of a machine for forming bars into horseshoe blanks provided with complemental reciprocating and rotating dies, an intermediate gear-wheel, spur gearing inteposed between said intermediate gear-wheel and each of said dies, a main-shaft, a driving gear, a friction clutch and a starting lever. 7

My invention further consists of amachine for forming metal bars into horseshoe blanks provided with complemental reciprocating and rotary dies, mechanism for actuating said dies, and means for automatically throwing said mechanism out of action at a predetermined point in the travel of the dies, whereby the blanks are automatically rolled of uniform and proper length.

My invention further consists of a machine for forming metal bars into horseshoe blanks provided with complemental reciprocating and rotary dies, a counter-shaft geared to each of said (lies, a driving shaft, and friction clutches and their accessories for connecting the driving shaft with the counter-shaft and with the rotary die, whereby the dies are operated more rapidly in one direction than the other; and my invention further consists of the improvements hereinafter described and claimed.

The nature, characteristic features and 0 scope of my invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof; and in which Figure 1,is a side elevation of a machine 5 for forming blanks for use in the manufacture of horseshoes embodying features of my invention and showing gearing for driving the complemental dies during the formation of a blank. Fig. 2, isa top or plan View of the machine showing devices for automatically checking the movement of the dies at the respective ends of their travel. Fig. 3,is a similar view to Fig. 1, showing the other side of the machine and illustrating means for rapidly returning the dies to their initial positions. Fig. 4, is an end view of the machine showing the main and counter shafts and their accessories. Fig. 5, is a sectional View taken on the line 55, of Fig. 6, and illustrating the detail construction of one type of rotary and reciprocating dies and also showing a horseshoe blank formed by said dies and adapted for use in the production of hind shoes. Fig. 6, is a front elevational view showing at the left hand side thereof dies adapted to produce blanks for hind shoes and at the right hand'side thereof dies adapted to produce blanks for front shoes. Fig. 7, is a top or plan view of the hind shoe blank illustrated in Fig. 5. Fig. 8, is a transverse section taken on the line 8-S, of Fig.

7; and Fig. 9, is a transverse section of a front shoe blank such as is produced by the dies shown at the right hand side of Fig. 6, illustrating the same provided with the required bevel.

In the drawings ct,isamain frame provided with horizontal ways a, and with standards a Arevolnble die or set of similar dies is or are formed upon the periphery of a cylinder 1) keyed or otherwise rigidly connected with a shaft 19, journaled in the standards a 0, is a reciprocating die or set of similar dies carried by a table d, working in ways a. The dies c,'may be flat or inclined. When the'die is fiat as shown at the left hand side of Fig. 6, it is useful in the production of a blankm, Fig. 8, for hind shoes, and when it is inclined as shown at the right hand side of Fig. 6, it is useful in the production of a'blank as, Fig. 9,for front shoes. The dies of the cylihder 1), Figs. 5 and G, are located between flanges y, that overlap the dies 0, of the table d, and comprise recesses y, in which the calks x are formed, creasers g and projections 1 that form the groove m and nail hole cavities 00 and a spur y that indents the'blank as at 03 and thus facilitates the operation of cutting the same into shoe lengths. By the employment of these dies horse and mule shoes can be rapidly and perfectly made, and from' one to six shoe-bars of different kinds or forms and adapted to be cut up into three or more calked or continuous calked or plain shoes can be made at the same time and-by one revolution of the cylinder b, and a corresponding movement of the table d, because these rocating die and with a gear-wheel 8 meshing with a gear f, keyed to one end of the shaft b.

The main driving shaft g, of the machine is journaled in the frame-work a, and is revolved continuously in the direction indicated by the arrow in Fig. 1, by means of a pulley and belt, or other power appliance, (not shown.)

h, is a driving gear loosely mounted upon the shaft g, and provided with one member 77., of a friction clutch, whereof the other member 71. is splined onto the shaft g, so that when the two parts 72. and 7?,2, of the friction clutch, are in engagement with each other, motion is transmitted from the driving shaft g, to the counter-shaft 6, through the intervention of the gears h and c and from the counter-shaft to the die 0, through the intervention of the rackf, and pinion e, and to the die of the cylinder I), through the'intervention of the gears e and f, so that the intermediate Wheel or gear 6 drives both of the dies through the intervention of suitable gearing.

During the rolling operation the iron bar may and in practice usually does offer more resistance to the movement of one of the dies than to the movement of the other of them, so that if the necessary motion were transmitted to one'of the dies and from it through theinterventionof suitable gearing to the other, the result would be that one of the'dies would tend to lag behind the other, whereby the calks and indentations wouldbe displaced and the blanks rendered useless.

In my invention the wheel e is'positively driven and imparts its motion through the intervention of distinct and separate mechanism to the respective dies, so that the latter are independently driven but are constrained to move in unison, thus insuring the proper relative disposition-of the calks and indentations in the finished blanks.

i, is an upright rock-shaft carried by the frame-work a, and provided at one extremity with an arm 2", connected with the member 77. of the friction clutch'and atthe'other'extremity with a tappet arm F.

j, is a starting lever pivotally connected with the frame-work a, and adapted to e11- gage the tappet arm 0?, in order to throw the member 7%, of the friction clutch into position for effecting the forward or operative movement of the dies through the intervention of the drivinggears.

i is a projection or stop carried by the rear portion of the table d, and adapted to be shifted by the forward motion thereof into contact with the tappet arm t whereby the latter is shifted into position for disengaging the respective members It and 7z ,of the friction clutch, thus automatically throwing the driving gear out of action. By these means the dies are automatically'stopped as soon as they have completed the operation of rolling a series of blanks suitable for being out up ITO into a number of lengths which after bending form perfect horseshoes. Thus the waste of material duetocuttingofi the uneven ends that would occur if the dies were permitted to roll blanks of various lengths, is avoided.

In, Fig. 3, is a pulley mounted loose upon the driving shaft g, and provided with one member Z, of a friction clutch, whereof ,the other member Z, is splined onto the shaft. This pulley 70, serves to impart motion to a pulley m, keyed to the shaft 1), through the intervention of a crossed belt 71, whereby the dies may be returned rapidly to their normal or initial position. t

0, is an upright'rock-shaft provided at its lower extremity with a radial arm 0', carrying the member Z, of the friction clutch,and at its upper extremity with a tappet arm 0 p, is a reversing lever pivotally connected with the frame-work a, and adapted to engage with the tappet-arm 0 and thus throw the member Z, of the friction clutch,into action, whereupon the dies are returned-to theirinitial positions through the instrumentality of the crossed belt n, and its com plemental pulleys, gear-wheels f and 6 rack f, and pinion 6.

0 is alug carried by the forward portion of the table d, and adapted to collide with the tappet-arm 0 in order to shift the same into position forthrowing the member Z, of the clutch out of engagement as soon as the dies.

have been brought to their initial positions.

The mode of operation of the hereinabove described. machine is as follows:Assuming that the parts are in. the position illustrated in Fig. 1, a number of bars of metal are placed side by side upon the table 01, whereupon the starting lever j, is depressed, thus throwing the gears h, e and f, into. action and causing the diesto roll the bars into horseshoe blanks. As soon as the blanks have attained the requisitelength for being cut up into pieces adapted to be bent into complete horseshoes, the lug 2' by contacting with the tappet-arm 2' automatically throws the gears 71, e and f out of action, where upon the movement of the dies is checked.

After the finished blanks have been removed from the table cl, the reversing lever 19, is depressed. This movement of the reversing 1ever throws the member Z, of the clutch, into engagement with the member Z thereof, so that the dies are run rapidly in a reverse direction through the instrumentality of the crossed belt n, and its accessories. As soon as the dies have regained their original or initial positions the lug 0 by contacting with the tappet-arm 0 automatically throws the member Z, of the clutch, out of action with the result that the dies and table d, are brought to rest in position for eifecting the formation of a second series of horseshoe blanks in precisely the manner hereinabove described.

It will be obvious to those skilled in the art to which my invention appertains that modifications maybe made in details without departing from the true spirit thereof, hence I do not limit myself to the exact construction and arrangement of parts hereinabove set forth, but t Having thus described the nature and objects of my present invention, what I claim as new, and desire to secure by Letters lPatent, is r t 1.
